Abstract

L'invention porte sur un trépan de forage de la terre comprenant un corps de trépan configuré dans sa partie supérieure pour une liaison à un train de tige. Un nombre sélectionné de lames fixes s'étendent vers le bas à partir du corps de trépan, et un nombre sélectionné de molettes sont montées pour une rotation sur le corps de trépan. Une pluralité d'éléments de coupe de molette sont agencés sur chaque molette et une pluralité d'éléments de coupe de lame fixe sont agencés sur chaque lame fixe. Selon des aspects de la présente invention, le nombre sélectionné de lames fixes dépasse le nombre sélectionné de molettes d'au moins un.
